Introduction 1.1. Vienna Vienna, the traditional gate between Western Europe, the Balkans and Eastern Europe has long been on the sidelines of the European economy and politics. Since the upheavals of the late 20
th
http://www.wikimirror.com/Vienna Vienna - city of culture, emperors and ballrooms – boasts trendsetting buildings designed by world renowned architects such as Otto Wagner, Adolf Loos, Hans Hollein and Coop Himmelblau. Always at the forefront of modern architecture, Vienna is proud of its impressive avant-garde residential developments and social housing projects built by the city government. Secession near Karlsplatz Urban development, guided by social consciousness, is evident not only in residential areas but also in the system of green beltways, the new recreational parks along the Danube river, an extensive network of cycle lanes and the metro system, currently being adapted to the needs of the handicapped. 1.2. The site But amid the impressive city planning, Vienna has its share of derelict areas. At the intersection of the western belt (Westgürtel) and the Vienna river valley (Wiental), two major city thorough-fares, two metro lines and the channelled Vienna River enclose a large, neglected area, divorced from the hustle and bustle of city life. An impressive steel trussed metro bridge by Otto Wagner towers above this waste land and mesh of urban infrastructure. In most cities you would find a bustling business centre on a site so close to the downtown area, sitting right on top of two metro lines and served by two main traffic arteries. So why then is this prime site a no-man’s-land, so evidently underused? Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 4 of 27 September 16, 2007 1.3. District boundaries and demographics The first reason may be found in the administrative structure of the city of Vienna which divides the city into 23 districts. Right at the heart of the competition site, the four districts Margarethen V, Mariahilf VI, Meidling XII and Rudolfsheim-Fünfhaus XV intersect. Concentrated more densely at the centre of each district, business, social and administrative activities are rather scarce at the periphery. At the intersection of four districts this scarcity of activities seems to have a negative effect on residential areas around it. They show the following distinct signs which in the future may lead to more social strain and even more neglect (charts from �� �� �� �� �� (All graphics from Stadtentwicklungsplan Wien 2005 STEP 05) Poly centric city structure Density of law offices Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 5 of 27 September 16, 2007 Density of health care / District numbers Socio-economic structure (education & living standard): green = low range / red = high range 1.4. Hidden past When you start to dig (literally) a little deeper you will find the second reason for this no-man’s-land. The big meadow at the heart of the perimeter was the site of the former Gaudenzdorfer gasworks. Built in 1855 and torn down in 1912, now only some well covered ruins remain. Right under the surface of the meadow, well hidden from sight and memory, old underground tanks filled with tar residue and toxic chemicals, such as cyanide (for more information on toxic waste try google with “gaswork” & “toxic waste”) are encapsulated with a clay cover, insulated, so one hopes, from rain water seeping into the ground. VI V XII XV Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 6 of 27 September 16, 2007 Gaudenzdorfer gasworks with river regulation works ca 1897 Only when a new branch of the metro was built back in the 1980ies was a small part of that toxic waste dug out of the ground under the most stringent safety measures and removed to another location. However, most of the underground ruins, and with them most of the toxic waste, still remains buried in proximity of the Vienna River and its ground water current. 1.5. Urban waste land With a background of unfavourable demographics and hidden toxic past, the site lay neglected for decades. To add insult to injury, several obstacles make development even more difficult: �� �� �� Inherent to a site already neglected is its tendency to attract a wide range of third rate infrastructure and services, necessary for the city as a whole but unfavourable for the site itself. Here, what’s left of open space is wasted for services such as: �� �� �� Gaudenzdorfer Gürtel, Burger King, gas station and tour bus parking as seen from Amid all this lies a public meadow. The very high level of constant traffic noise, insufficient accessibility and the few passing pedestrians, turn the meadow more into an oddity than an asset, even though the meadow itself is remarkable for its biodiversity. Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 7 of 27 September 16, 2007 1.6. Remarkable potential Despite the negative aspects mentioned, the site is nevertheless marked for better use.

The project New Crowned Hope For artist Peter Sellars conceived an encompassing tribute with a number of artists from different fields of art working under the common title As part of this tribute, a group of students led by Peter Sellars worked on a series of interdisciplinary projects concerning the area around Theory and Practice” a book with the title Aimed at giving an answer to the problems so evident in this area but accepting all infrastructures for road traffic, metros and the Vienna River as they are at present, the project restricted itself to the wasteland at the heart of Illustration from the book Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 9 of 27 September 16, 2007 2. The defining elements of the site The site covering an overall area of more than 70’000 m landmarks and a unique combination of special features single it out for development. 2.1. Vienna River Certainly the most defining element is the Vienna River itself. Taking up a series of small tributaries in the hills of the inner city and finally into the Danube canal. On its course, the river passes a series of famous landmarks such as the palace of and the bustling built at the end of the 19 the Vienna Valley metro line, separated from the tracks only by a sturdy granite wall. Flowing through the ever more densely populated city, the Vienna River is hemmed in step by step first between levies, then by a canal with masonry walls and riverbed. As it reaches the limits of the 6 the longest being from Naschmarkt to Stadtpark. It is one of these tunnels that served as a dramatic back drop for the 1949 film classic http://en.wikipedia.org/wiki/The_Third_Man Vienna River canal under construction west of Vienna River tunnel under construction near Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 10 of 27 September 16, 2007 Inside the competition perimeter, the Vienna River first runs in the open masonry canal. Then, just before reaching the U6 metro bridge, the river flows into a 380m long tunnel until it reaches metro station at the eastern end of the competition perimeter. http://www.wien.gv.at/umwelt/wasserbau/gewaesser/wienfluss.html 2.2. Metro lines Metroline U4 for most of its stretch runs parallel to the Vienna River canal. While the first stretch from the Prater up to Naschmarkt is completely underground, the second stretch is an open canal much like the Vienna River canal. On her second stretch from Naschmarkt to the terminal station at Hütteldorf, U4 runs in a tunnel only for the short distance between the metro stations Margaretengürtel and Längenfeldgasse, right inside the competition perimeter. Metroline U6 follows the Westgürtel as a mostly elevated track, crosses the Vienna river valley on the girder bridge track at Längenfeldgasse Metro station where it joins with U4. After Längenfeldgasse station, U6 leads on to the southern districts of Vienna. For both metro lines as well as for the Vienna River canal, Otto Wagner was the engineer and architect responsible for this impressive work of modern city infrastructure. http://www.haunted-memories.net/userfiles/subwaysystem.html http://progs.wiennet.at/ottowagner/index.htm http://en.wikipedia.org/wiki/Otto_Wagner 2.3. The landmark bridge Brücke über die Zeile Certainly the most visible and attractive feature of the site is the Otto Wagner and inaugurated 1898. From north to south, the first span of the bridge reaches over the River canal, while the second span reaches over the old underground track of the metro line U4. Two massive granite towers form the two pillars at each end of the bridge. Between the first and second span, a comparatively narrow granite pillar rises above the dividing wall between the Vienna River tunnel and the metro tunnel. As the bridge crosses both these tunnels at an angle, the pillar sitting on top of the tunnel walls is set diagonally to axis of the bridge. The two spans of the steel girder bridge are made of bolted steel profiles while the ramp-bridges on both sides are arched structures made of red bricks. Brücke über die Zeile Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 11 of 27 September 16, 2007 2.4. The road thoroughfares Other than its size, importance to the city and negative local impact, nothing is noteworthy about road traffic on the site. Following the outlines of the former gasworks, it forms a giant circular traffic system with a 12’000 m the four neighboring districts effectively from each other and thus accentuates the peripheral situation far from the district centers. Primary roads (grey), metro lines (brown and violet) and sub centers (violet circles) Linke Wienzeile looking south to Margaretengürtel (right hand corner: Brücke über die Wien Zeile) Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 12 of 27 September 16, 2007 3. The Goal With imaginative repositioning, and some adjustments to the traffic infrastructure, the existing potential of the site can be brought to life. Improvements can be achieved that will allow to change this neglected site into an attractive place of public activity and will give a positive impulse to the revival of the adjoining residential and business areas. Three objectives stand at the focus of this competition: 3.1. Quality of life From Wikipedia, the free encyclopedia “The well-being or quality of life of a population is an important concern in economics and political science. It is measured by build, social and economic environment. There are many components to well-being. A large part is standard of living, the amount of money and access to goods and services that a person has; these numbers are fairly easily measured. Others like freedom, happiness, art, environmental health, and innovation are far harder to measure. This has created an inevitable imbalance as programs and policies are created to fit the easily available economic numbers while ignoring the other measures, that are very difficult to plan for or assess.” http://en.wikipedia.org/wiki/Quality_of_life To improve quality of life we propose that the scarcely used wasteland over the former gasworks and to both sides of the public and private use �� all directions and an outdoor living room for the densely built up neighbourhood. The common should offer facilities for the very young to play and adventure, to older generations the chance to relax, to experience nature and to meet friends. �� with both parents working or single parent families will find an infrastructure with day care, small shops and a safe outdoor which meets their needs. �� (handicraft, arts, language skills etc), club rooms and café. �� sport facilities Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 13 of 27 September 16, 2007 3.2. Sustainability To many, sustainability is little more than a trendy slogan. To city planners and architects, it must be a guideline along which to act. Excerpt from UNECE Sustainable development - concept and action When the World Commission on Environment and Development (Brundtland Commission) published its report in 1987, it presented a new concept - sustainable development. The concept became one of the most successful approaches to be introduced in many years. In fact, it helped to shape the international agenda and the international community's attitude towards environmental development. The Brundtland Commission's report defined sustainable development as "development which meets the needs of current generations without compromising the ability of future generations to meet their own needs". The concept supports strong economic and social development, in particular for people with a low standard of living. At the same time it underlines the importance of protecting the natural resource base and the environment. Economic and social well-being cannot be improved with measures that destroy the environment. Intergenerational solidarity is also crucial: All development has to take into account its impact on the opportunities for future generations. http://www.unece.org/oes/nutshell/2004-2005/focus_sustainable_development.htm The neglected state of the competition site offers a challenge to sustainability in all three fields listed above. However, with the goals of this competition, not all challenges of a sustainable city can be met. We propose the following steps toward an improved sustainability: �� very economic and intelligent way, for public parks, a residential area and a community centre. �� �� the area to its inhabitants. �� �� and activities aimed at smooth integration of immigrant residents. �� public spaces. �� quality and attractiveness and by raising the level of education and social skills among the youth in the area. Unfortunately, to give access to the river will be of only limited ecological impact, as the hard surfaced riverbed is to be kept as is. Still, it is a small step towards a more natural environment and to rivers less bound and gagged by our built environment. The chance to experience the element of water in its basic form, as a small river on the way from the may create more awareness and respect for a natural asset that shaped an important part of Vienna’s topography. The biggest impact could certainly be made by cleaning up the toxic waste now well hidden. Evidently, the huge cost of such an endeavour ranging in the tens of millions of Euros has prevented the City of Vienna to undertake the necessary steps. For the purpose of this competition we will accept that the toxic waste will remain encased in the underground. Nevertheless, the long time risk of Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 14 of 27 September 16, 2007 toxic waste seeping into the underground water course of the Vienna River Valley should make the cleanup a top priority. Otherwise, sustainability will be manifest in many conceptual and technical details of your design. At the requested scale of project however, factors like energy consumption, environment friendly materials etc will be less evident in your design. Even so, as a future architect you will keep these criteria in mind! 3.3. Economic viability / Environmental Economics No city planning or development activity can take place without a close regard for economics. As many “products” of city planning such as city parks, an emission free environment, a socially intact neighbourhood or, in a more general way, quality of life, have no direct financial yield, these “products” quite often are left unaccounted for. into account the missing elements of external costs and yield. From Wikipedia, the free encyclopedia “Central to environmental economics is the concept of an externality. This means that some effects of an activity are not taken into account in its price. For instance, pollution in excess of the socially "optimal" level may occur if the prices a producer pays do not include the impacts (costs) experienced by those adversely affected. … In economic terminology, these are examples of market failures, and that is an outcome which is not efficient in an economic sense. Here the inefficiency is caused because too much of the polluting activity will be carried out, as the polluter will not take the interests of those adversely affected by the pollution into account. This has led to controversial research into measuring well-being which tries to measure when pollution is actually starting to affect human health and general quality of life.” http://www.answers.com/topic/environmental-economics?cat=technology At the time the Gaudenzdorfer gasworks were built, run and later torn down, environmental economics was not yet a topic. It was left to later generations to clean up the toxic waste and to pick up the bill. Today, the huge costs of sanitation and renewal for converting this neglected area into an attractive environment can only be set off by a development of high density combined with high yield functions such as prime office space, luxury shops or shopping malls. Neither seems to be suited for this area, since primary demand is for public space and community infrastructure. For the purpose of this competition, we will therefore restrict ourselves to a solution that generates income on only a small part of the perimeter. With about 2% of the surface of the competition perimeter we may realize an added value on the land in the range of 5 to 10 million Euros which will pay at least part of the bill from reorganizing traffic inside the perimeter. No figures are available on the added value to the neighbourhood which will profit from a much more attractive environment and from regained urban quality. Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 15 of 27 September 16, 2007 4. New inputs With some rather small alterations to the existing situation conditions for future developments can be markedly improved. 4.1. Relocate road traffic on Gaudenzdorfer Gürtel (mandatory) The existing road traffic infrastructure still follows the outlines of the former Gaudenzdorfer gasworks. The intense traffic on these important north-south and east-west corridors blocks any development in the area, unless a change to the traffic system is made. Today, north-south traffic (red) crosses the Gaudenzdorfer Gürtel joins the tramway line (grey). East-west traffic (yellow) runs on ( By pushing the north-south track (red) towards the tramway line (grey), the wasteland over the former gasworks becomes accessible and can be linked up with the residential area behind Dunklergasse. The relocated tracks form the new valid basis for all competition projects! N N Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 16 of 27 September 16, 2007 4.2. Cut back the metro line maintenance track (optional) Back in the 1980’s, the track of metro line U4 was relocated in a new tunnel (green dashed line) to the south of the original tunnel. Today, a maintenance track (pink line) uses the old tunnel. The track runs off from dotted line) shortly after passing under the The track is used for loading building materials onto the maintenance trains. As these trains are limited to 65 meters in length, the maintenance track can be shortened considerably, although for loading and unloading it must remain uncovered. If needed, you can push the end of the track towards the east to a point just in line with the upriver or western end of the middle pillar (white rectangle, pink circle 1) of the entrance to the tunnel must then be pushed back as well and can be relocated as far back as where Gaudenzdorfer Gürtel As the pushed back loading track (pink dotted line) would seldom be in use, it could even be integrated into an area open to the public; the rails could be set into the pavement much like the rails of a tramway line. Competitors are free to make use of the possibility offered. 4.3. Opening the Vienna River tunnel (optional) Originally the Vienna River tunnel should have taken up a much longer part of the river’s course through the city. Probably for lack of funds, only parts of it were ever constructed. To accommodate the needs of the traffic intersection at Gaudenzdorfer Gürtel, one of only two tunnel stretches was constructed here (the second being the stretch between Today, the first hundred meters of this tunnel (blue shaded area) directly under the Zeile track, conditions for access to the river could be improved. Competitors are free to make use of the possibility offered. 1 2 Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 17 of 27 September 16, 2007 5. The Task 5.1.

Parking Other than the parking spaces to be replaced together with the Burger King (§ 6.4 / H6), which will be available for all other businesses as well, parking spaces for private cars are not part of the program. An important percentage of city residents do not own a car; to offer parking spaces would needlessly add to costs. Furthermore, in an area so well served by public transport, the proposed strategy is certainly the sustainable one.

Regulations, Restrictions WARNING: Even though a lot of regulations, restrictions and technical details are mentioned in the chapter hereafter, the emphasis is still on a project centered on quality of life, sustainability and economic viability / environmental economics. Do not lose sight of the main topic “Access for All” and the title of the task “To Reclaim the Public Ground”! 7.1. Building restrictions No building restrictions such as maximum length, width or height are given for the purpose of this competition. 7.2. Height indication on plans All height indications on plans refer to the so called back to the 19 zero level for the new height measurements was 4m above the average water level of the Canal measurements were taken. In reference to the Adriatic Sea (Triest at that time was still an Austrian city) zero height is 156.68 meters above sea level. http://www.wien.gv.at/stadtentwicklung/stadtvermessung/geodaten/festpunkt.html 7.3.

Bicycle Path and Bicycle Bridge The new bicycle and pedestrian pathway is linked to the existing net at the following four points: Blue: Existing net of bicycle pathways / Red: Missing links 7.5.1. Connection point south The connection point with the bicycle path leading south is situated at the intersection of Gaudenzdorfer Gürtel park between a level crossing of 7.5.2. Connection point west The connection point with the bicycle path leading west is north of the at River Canal is currently being discussed by the authorities. Competitors may propose such a pathway and the link up with it. 7.5.3. Connection point north The connection point with the bicycle path leading north along Gumpendorfer Gürtel is situated in the small park to the north-east of the branch off from Gürtel.

Connection point east The bicycle path joins the existing bicycle path along with Metro station (general area indicated with the green circle). Margaretengürtel 5.2 m’ above the tramway lines. The ramp leading up from the east towards the crossing point is not part of the competition. Competitors must develop their project only from the crossing point on towards the west. The solutions for the eastern ramp bridge shown on the following plans are for general information only. City of Vienna: Feasibility study for a bicycle- & pedestrian bridge over Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 25 of 27 September 16, 2007 7.5.5. Inclination and width of ramps for wheelchairs and bicycles 4% unlimited length 5% for a 10m length 7% for a 5m length 8% for a 2m length 12% for a 0.5m length All ramps should terminate with a landing of at least 1.50m in length. Minimum width for two way traffic is 4 m’. 7.5.6. Free height above city streets At bridge crossings with city streets a free height of 5.00 m’ must be kept. 7.5.7. Free height above tramway lines At bridge crossings with tramway lines a free height of 5.20 m’ must be kept. 7.6. Brücke über die Zeile 7.6.1. Historic monument No changes or alterations to the bridge structure are allowed. Keep in mind the axis of view onto the bridge. 7.6.2. Foundations The existing foundations of the bridge reach lower than the river bed. From a technical point of view, excavations near the bridge down to the level of the riverbed are possible. 7.6.3. Space under the bridge arches The spaces under the arches of the ramp bridge now used for depots and workshops can be used for purposes of the competition task. No replacement inside the competition perimeter need be offered for the functions now located under the arches. 7.7. Buildings over metro tunnels 7.7.1. Old metro tunnel (maintenance track) No buildings other than small one-story structures are allowed over the old metro tunnel. Pillars for an eventual bicycle bridge can be positioned directly over the tunnel walls. Roadways and a park over the old metro tunnel are permitted. The existing foundations of the tunnel reach lower than the river bed. From a technical point of view, excavations near the tunnel down to the level of the riverbed are possible. 7.7.2. New metro tunnel Buildings up to two storys with slab foundation are allowed over the new metro tunnel. Pillars for an eventual bicycle bridge can be positioned directly over the tunnel walls. Roadways and park over the new metro tunnel are permitted. The existing foundations of the tunnel reach lower than the river bed. From a technical point of view, excavations near the tunnel down to the level of the riverbed are possible. Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 26 of 27 September 16, 2007 7.8. Buildings over Vienna River tunnel No buildings other than small one-story structures are allowed over the Vienna tunnel. Pillars for a eventual bicycle bridge can be positioned directly over the tunnel walls. Roadways and a park over the Vienna tunnel are permitted. The existing foundations of the tunnel reach lower than the river bed. From a technical point of view, excavations near the tunnel down to the level of the riverbed are possible. 7.9. Flooding / high water Vienna River flood 1976 http://www.iiasa.ac.at/Research/RMS/dpri2002/Papers/Compton.pdf Even though the Vienna River runs very low at most times, the danger of flooding must be taken into account for all new structures along the river. Two different levels of flooding are defined (see section plan 3_1_6): Schindler Award for Architecture 2007 / 2008 «Access for All» 2_2_1 Task Page 27 of 27 September 16, 2007 7.9.1. Normal river flow No changes to the slightly V-shaped masonry river bed are permitted. 7.9.2. Floods with a recurrence of 100 year On the stretch of open canal downriver from Längenfeldgasse metro station, the 100 year flood level is a line running in parallel and 3.7m above the river bed. Below the 100 year flood level, no fixed structures that can be damaged or washed away by floods are permitted. Exception: Mobile furniture that can be removed within an hour. No openings to buildings are allowed. No trees are permitted. 7.9.3. Floods with a recurrence of 1’000 year On the stretch of open canal downriver from Längenfeldgasse metro station, the 1’000 year flood level is a horizontal line 20m above Vienna zero. Below the 1’000 year flood level, no fixed structures that can be damaged or washed away by flooding are permitted. Exception: Mobile furniture, park equipment, storage shed, sun roofs etc. No openings to buildings are permitted. Exception: Storage rooms for park furniture. Trees are permitted. (Compared to the standard cross section of the open Vienna River canal, the cross section of the river tunnel is narrower. This hinders the water flow at the tunnel entrance where a partial back-up occurs. As a consequence, the 1’000 year high water mark does not run in parallel to the river bed but is more or less horizontal at a height of 20m above Vienna zero). 7.9.4. Metro maintenance track The danger of flooding the extensive net of metro tunnels is considerable. If the dividing wall between the maintenance track § 4.2 is to be lowered for a better access to the river, flooding of the tunnels would occur with a 1’000 year flood. As the maintenance track is seldom in use, it can be blocked off by a semi-permanent dam or floodgate. You need not concern yourself with the details of such a device. 7.10. Toxic waste Because of the toxic waste hidden in the underground, no subterranean buildings or parts of buildings other than foundation pillars are allowed in the area marked 3_1_1.
